Claims.

a rotary gear carrying ice shaving knives, said 7 gear being mountedwithin a platform forming a cover for the housing and a support for anelectric motor which drives the gear.

The main object of the present invention is to provide an improvedconstruction of machine which is sharper, easier running, more durable,and embodies novel means for supporting the motor and drive gearing toreduce vibration and wear and tear on the machine.

A further object of the invention is to provide a novel construction andarrangement of gear casing to enclose and lubricate the gearing and sealthe lubricant and gear containing means against the access of shaved iceand water thereto.

With these and other objects in view, the invention consists in thenovel construction, arrangement and combination of features hereinafterfully described and claimed, and shown in the accompanying drawings, inwhich:

Fig. 1 is a front elevation of the machine;

Fig. 2 is a top plan view thereof;

Fig. 3 is a sectional plan view taken on line 3-4 of Fig. 5;

Fig. 4 is a similar view taken on line 4--4 of Fig. 5;

Fig. 5 is a vertical transverse section taken on line 5-5 of Fig. 2;

Fig. 6 is a detail section on line 6-6 of Fig. 5; and

Fig. 7 is an enlargeddetail section through a portion of the gearchamber.

Referring now more particularly to the draw ings, I represents the baseof the machine, which comprises a housing to receive the shaved ice andwhich is preferably formed of a cast frame normally open at bottom andtop and having its sides open and closed except at the front by panels 2of Plexiglas clamped to corner posts 3 of the frame by brackets At thefront the housing is provided with a door 5 of suitable type, whichcloses the front opening, through which, when the door is opened, theshaved ice may be removed. A shaved ice supporting pan or tray 6fing'erpiece presses the button 22, or sooner by I closes the bottom ofthe housing and is provided with a water drain outlet 1. I

At its top the machine is provided with'a cabinet or receptacle 8 tohold a block of ice from which the ice is to be shaved. This rests andis.

supported at its baseon the top orcover 9 of a gear casing'includingsaid cover and a base section Ill, the construction of whichcasing will be more fully hereinafter described. The gear cas ing alsoforms a support for an electric motor I I.

A suitable bracing means I2 is provided to mutually brace the receptacle'8 and the motor" against vibration andother strains, and to main-" tainthem'in proper alignment. i

The receptacle 8 is open at its bottom and is provided with an accessdoor I3 and is suitably secured at its bottom to the cover 9 in linewith anopening I4 therein. At its top the receptacle; is closed by acover I5, which may be either fixed q or removable, and which is formed:with a guide passage 16 and a chamber I! in which is arranged a switchbox I8 which in practice is suitably condescribed. This disk maybepositively guided against rotation in its up and down movements and isprovided with teeth24 to engage the block of ice. A rod 25 is attachedat its lower end to the disk and extends at its upper end outwardlythrough the guide passage I6 in the cover I5 and is provided with a knob26 whereby the rod and disk may be raised and lowered. .The rod isadapted to be raised to bring the disk to the dotted line position shownin Fig. 5, so that it will rest on a block of ice inserted in thereceptacle through its doorway. A pin 21, attached to the cover I5 by achain 28 or thelike, is adapted to be passed through a hole 29 in therod to hold it and the disk in raised position while the block of ice isbeing inserted. Mounted on the upper end of the rod is a fingerpiece 30.This fingerpiece is adapted to engage the button 22 at the end of thedownward movement of disk 23, whenthe shaving of an ice block iscompletedQto stop the operation of the motor. At the start of a cuttingoperation the operator presses the starting button 2|, after which theoperation is automatic to the end of the shaving of the block, when theice receptacle, and which closes the top of the bottom housing andsupports the receptacle and the motor; As; shown, the base section 9" isformed to provide an annular oilreceiving channel 3| to hold oil to acertain high level below the level of its inner wall 32, the outer wall33 which extends to a slightly higher leveL-than-the; inner wall. At oneside said section has an offset 34 in which is an upstanding boss 35andwhich underlies the motor concentric with its shaft 36. This shaftcarries a drive pinion 3T and is provided with a reduced end 38 havinga: stepped bearing in a recess 39 formed in the boss 35 An: annularhanged pedestal.Mlv is in: communication with the offset portion- 34 andisflm edior: attachment tosaid; ofiset portion and motor and forms asupport for. the motor. inner wall; 32. oi the'channeled section H}supports a plurality of vertically disposed bearing rollcrsl twhich arearranged within. the. oilchannot; and at its upper said wall- 32." is'pro- The I '4 thrust falling on the cutter gear during a cuttingoperation.

From the foregoing description, taken in connection with the drawings,the operation of the machine will be readily understood without a.further and extended description. A block of ice is introduced into theice receptacle above the raised follower, which is then released fromits holding pin to adapt the follower to exert downward pressure on and:travel; downward with. the ice block. The operator thereupon pressesbutton 2| which starts the motor into operation to drive the cut- Iter'gear, the knives of which shave ice from the vided with aninward-lyextendingannular hori-- zonitalfflange. lz 'reccssed'zto receive asealing ring of: felt or "other suitable absorbent sealing material?

Asshown, they block. The. shaved ice passes throughthe openings in the cutter gear into the housing below, tromwhich theshaved ice may be removed as and when desired. In the operation abovedescribed the working parts are sustained against the working thrustsand. lubricated so that an easy working action is obtained and wear andtear on the working. parts. reduced, thus providing a strong anddurablemachine theworking parts of which are protected. and not liable to beeasily injured or rendered unserviceable. The construction of the.machine also adapts the gear mechanism' t-o be applied andremoved asaunit, and the knives to be. removed. for reshar pening whenever.required by lifting ofif thecover of the gear casing. olosed.-i n1e.t56in the. cover 9v and a drain valve- -51. at. the bottom of. the oilchannel-may be pre-v I changes the form, constructionand arrangemcnt' ofparts, falling-withinthescope of the appended claims, may be madewithout departing from thespiritor sacrificing any of the advantages of.the invention.
